The inheritance of the dehiscent pod character was investigated in two recombinant inbred populations using a simplified correlation analysis. The approach identified three regions on the pea genome that affect the expression of pod dehiscence. The region on linkage group III corresponded to the expected position of Dpo, a gene known to influence pod dehiscence. A locus on linkage group V appeared to have a slightly smaller effect on expression of the phenotype. The third region was observed only in one cross, had a greater effect than Dpo, and was postulated to be yellow pod allele at the Gp locus
